Abstract

The numerical investigation of the landing and take-off processes of the NACA4412 airfoil on a platform is conducted to study the mutational ground effect. The incompressible Unsteady Reynolds-Averaged Navier-Stokes (UNRANS) equations and the Shear Stress Transport k-ω (SST k-ω) turbulence model are discretized using the finite volume method. The dynamic layering technology is adopted to deal with the relative movement between the airfoil and the platform. The landing and take-off processes can be divided into four regions based on the lift characteristics and flow physics. Except for the static ground effect, the airfoil undergoes the upwash flow in landing and the downwash flow in take-off condition. It should be noted this study on mutational ground effect is first of its kind reported in the gound effect literature for the first time.
